If you prioritize gaming, especially HDR gaming, and are also interested in high-quality media consumption with vivid colors and high brightness, the CoolerMaster GP27U, despite its premium price, is a strong choice as it offers a high refresh rate and excellent image clarity. On the other hand, if your primary focus is on productivity with a unique aspect ratio for multitasking and your budget is a concern, the LG DualUp 28MQ780 being less expensive and suitable for digital photo editing, may better meet your needs, while being less ideal for gaming and media consumption due to its lower refresh rate and color performance.
